After Marshall Bennett experimented with the Eternal Motor City Blackbird tatoto ink, he suggested adopting the Blackbird pigment for his gray wash set. Together Eternal Ink and Marshall reworked his set. “We are taking this set back to the essentials and simplifying the values,” said Marshall Bennett. The new gray wash set uses the Blackbird ink pigment and is divided into 4 stepped values of black: a 20%, 40%, 60%, and 80% value. With just 4 value steps and very distinct 20% value breaks, this is a highly efficient gray wash set.
